Answer:

D) 42.16

Total: $553.13

Step-by-step explanation:

Multiply the subtotal, 510.97, by 8.25%. To do that just turn the 8.25% into a decimal which is 0.0825. The answer to that would be 42.155025 and rounded it would be 42.16 so the tax would be $42.16.

The total to the entire thing would be $553.13 since you just add the tax and subtotal together.

Answer: D 42.16

Step-by-step explanation: 510.97(subtotal)x8.25%(sales tax)=42.16

Don’t forget to move the decimal 2 places to the left on the sales tax when multiplying(.0825)

First Part:
A cube has all equal sides and therefore the formula of:
-Volume of Cube=side³
                           =3³=27 cm³
-Volume of Cuboid=Area of base×Height of prism
            1st prism   =4×3×1=12 cm³
            2nd prism  =7×4×9=252 cm³
            3rd prism   =3.5×5×6=105 cm³
Second part:
Volumes are given with one side missing
            V=Area of base×Height of Prism
1st prism
         360=6×12×x
         360=72x
         \frac{360}{72}=\frac{72x}{72}
         5 cm=x
Check: V=6×12×5=360 cm³
2nd question:
         break it into 2 parts:
1st: find the volume of the first cuboid: 
       V=3×3×4=36 cm³
So now we know the volume of the second cuboid since both of them have the same volume.
2nd: 36=6×4×x
        36=24x
\frac{36}{24} =  \frac{24x}{24}
 1.5 cm=x
         Check: 1.5×6×4=36 cm³

How is the formula for the circumference of a circle derived? Drag and drop the correct word into each box to complete the expla
n200080 [17]

Answer:

diameter

circumference

\pi

diameter

Step-by-step explanation:

First, find the length of the diameter (d) and the length of the circumference of the circle (c).

Next, divide the length of the circumference c by the length of the diameter d and set up an equation

\dfrac{c}{d}=\pi

where the ratio equals to \mathbf{\pi } (the definition of \pi)

Then, solve the equation for the circumference c:

c=\pi d

Finally, substitute 2 times the radius for the diameter

c=\pi \cdot 2r=2\pi r

You do not need to flip the inequality sign when solving the inequality -3 t + 7 ≥ 9.
NemiM [27]

For this case we must resolve the following inequality:

-3t + 7 \geq9

Subtracting 7 from both sides of the inequality we have:

-3t \geq9-7\\-3t \geq2

Dividing by 3 to both sides of the inequality we have:

-t \geq \frac {2} {3}

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

t \leq- \frac {2} {3}

Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.

ANswer:

False. It is necessary to change the sense of inequality
